Humming noise
Hey there,

So I've been poking around the forums and been searching, and can't find an answer.

I recently bought my 01 325ci at around 77k with the top needing some "manual assistance." I'd tried it a few days after and literally nothing. I've paid to get it coded. They came up with the main pillar position switch being grounded and the top up button is permanently on. I've simply unplugged and replugged both switches and then I'm back to square one where there needs to be manual assistance.

Now when I try it, it unlocks at the windshield and lifts a bit then I hear humming and a few clicks then nothing.

Also I plan on doing a proper intro once the top works properly.

Thanks for any help,

Check your fluid level. It is behind the left side trunk carpet. There is a circle molded into/on the fluid tank. Top has to be fully stowed (down) to check the level.

Switches will will set a code if they are pressed too long. Like when you keep pushing the button waiting for it to do something.

Both of my open & close switches had shorted codes. Filled my fluid up and cleared all the codes. All was good until the fluid ran low again.

Thanks I'll check the fluid and report back with the results of my adventures.

So it's been a while but I checked the fluid level and it's full. I'm beginning to think it might be the motor?...
